Y. I Application June 19, 1934, Serial No. 731,372 6 Claims. (01.4-109) This invention relates to means for applying deodorants and disinfectants to drain pipes and one object of the invention is to provide an inexpensive device which may be easily placed in position or removed when the necessity arises and which will hold the deodorizing and disinfecting chemical so that dislodgment and loss of the chemical will be avoided and replacement may be very easily effected. It isa particular object of the invention to provide a structure which will admit flushing water to the drain pipe and which willdirect the dissolved chemical into the path of the inilowing flushing water whereby the chemical will be carried positively into the drain pipe to act upon any matter which tends to cling thereto. It is also an object of the invention to so construct the holder that the dissolved or liquefied chemical will be caused to flow down the inner wall of the drain pipe in contact therewith so that any matter which might tend to cling thereto will be very efiectually removed and carried to the sewer. The invention is illustrated in the accompanying drawings and consists in certain novel features which will be hereinafter first fully described and then more particularly defined in the appended claims.

In the drawingsr' Figure 1 is a perspective view showing the improved holder in working position.

Figure 2 is a diametric section on a larger scale.

Figure 3 is a plan view of the holder.

Figure 4 is a horizontal section on the line 4-4 of Figure 2.

V Figure 5 is a diametric section through the holder showing a construction diifering in form from that shown in Figure 2.

Figures 6, '7 and 8 are diametric sections showing other forms of the invention.

Figures 9, 10, and 11 are also diametric sections showing diiierent forms of the invention.

Referring more particularly to the drawings by identifying numerals, the reference numeral I indicates a body or cap of dome-like form having openings 2 through its sides to admit flushing water from the basin 3 surrounding the de vice so' that said flushing water will find its way to the drain pipe, indicated at 4. It will be noticed, upon reference to Figure 2, that the drain pipe is shown as having an annular radial shoulder 5 extending from its upper edge and a rim 6 rising from the edge of said shoulder while the lower edge or open bottom of the body I rests upon the shoulder 5 and abuts the rim 6 so that the body isthus properly centered over the drain pipe and is held against lateral displacement. In the top of the body or cap I, there is provided a central recess 1 adapted to receive a cake 8 of some deodorizing and disinfecting chemical which will be slowly volatile 5 and which will be effective in maintaining the drain pipe in a sanitary condition. The recess or chamber 1' is shown as of a circular outline concentric with the outer surface of the cap 5 I and an outlet passage 9 extends downwardly 10 from said chamber, said outlet passage being formed through a depending rim orring ill which is integral with the body or cap. Integral with the lower edge of the ring Ill is a shelf or deflector H immediately above which radial pas- 15 sages F2 are formed through the ring for the escape of the dissolving or liquefying chemical. It is to be especially noted that the diameter of the shelf or deflector H is greater than the diameter of the ring l0 but less than the inner diameter of the cap or body I so that there will be an open space between the deflector or shelf and the inner wall of the cap through which the dissolving or liquefying chemical may flow. It

it also to be noted that the diameter of the shelf 25 is greater than the diameter of the waste pipe so that the chemical escaping over the edge of the deflector will drop onto the shoulder or flange 5 of the waste pipe and will then flow over the same to the bore of the waste pipe and will 30 trickle or flow down over the inner surface of the pipe in contact therewith. The flow of the dissolving or liquefying chemical will be accelerated by the flushing water which is admitted whenever the flushing operation is necessitated 35 or deemed desirable. This flushing water will tend to accumulate upon the floor or base 3 surrounding the waste pipe and will flow through the openings 2 to find its way tothe waste pipe with considerable force so that any matter which 40 might tend to lodge in the waste pipe will be carried oif to the sewer. The particular nature of the chemical is not essential although I contemplate furnishing a chemical which I have found to be highly efiicient as a deodorizer and 45 disinfectant and by the use of which all ofiensive odors have been eliminated from Waste pipes which have been treated.

While the openings 2 are shown in the form of obliqueslots, they may be of any preferred 50 outline. It will also be understood that. the chemical may be in the form of an imperforate solid cake although it is shown with a central opening therethrough to facilitate the action of a liquid thereon. V

In Figure 5 is shown a form of the invention in which the body 33 has a chamber 34 in its upper end to receive the chemical cake 8 and a passage 35 extends downwardly from the center of said chamber or recess 34. In the lower portion of the passage 35, a web 36 is formed and vertical openings 31 are provided through this web immediately adjacent the wall of the passage to permit escape of the stream descending from the chemical cake. The web 36 is integral with the body of the holder and also integral with and depending from the web is a deflector 3B which has its sides flared toward the side wall 39 of the lower portion of the body and terminates a short distance from said body so that the stream flowing down over the deflector will be diverted toward the side and will discharge directly onto the inner wall of the drain pipe. In this form of the invention, the water-admitting openings 40 are formed below the upper end of the deflector and the body is formed with an annular flange 4| which seats upon the annular flange of the drain pipe.

In Figure 6 there is shown a holder comprising a body 58 of a general dome-like form having a central recess or opening 59 in its top to receive a cake 60 of chemical which, in this instance, is shown as having a diameter less than the diameter of the recess or chamber in which it is received so that a space will be provided around the edge of the chemical to facilitate the escape of the volatile liquefying or dissolving elements. The chemical cake rests upon a web or shelf 6| which extends across the lower end of the recess or chamber 59 and has outlet ports 62 extending therethrough at its edge. A neck 63 is formed integral with the web BI and depends below the same, terminating in an annular deflector 64 which projects laterally from the neck and terminates in spaced relation to the wall of the holder of the body 58. Water-admission openings 65 are formed through the body below the deflector 64 and the internal diameter of the body is somewhat greater than the diameter of the drain pipe so that the chemical dripping from the edge of the deflector 64 will not pass directly into the drain pipe but will drop onto the upper end thereof and then flow over onto the inner wall of the pipe.

In Figure "I, the body 66 is similar to the body 58 shown in Figure 6 and has water-admission openings 61 through its side near its lower end. The chemical cake 68 rests upon a spider comprising a central circular rim or ring 69 and radial fins 70 extending from said ring 69 to the wall of the body and formed integral therewith. Outlet ports H are formed through the lower portion of the ring 69 and the dissolving chemical may flow through the interior of the ring to these ports and also over the outer wall of the ring in the spaces between the fins, as will be understood. Below the ports H, a deflector I2 is formed integral with the ring 69 and has its side or edge flared toward the side wall of the body but terminating in spaced relation thereto and preferably having its bottom side flush with the lower ends of the fins l0 and in a plane with the lower sides of the water-admission openings 61 so that the inflowing flushing water will commingle with the descending chemical and carry it into the drain pipe, it being noted that the bottom diameter of the deflector is greater than the inside diameter of the drain pipe.

In Figure 8, there is shown a holder in which the body 13 is of the same general form as that shown in Figures 6 and '7, but in this form 0! the invention the chemical cake is received in a recess 14 in the top of the body having a central opening 15 in its bottom. At the lower end of the opening or passage 15 there is formed a web 16 having outlet ports I! therethrough at its edge and on the underside of this web is formed a neck 18. The body is shaped to present a horizontal surface 19 flush with the lower ends of the ports 11 and a horizontal shelf or deflector is formed integral with the lower end of the neck. The shelf 80 terminates in spaced relation to the side wall of the body but is of greater diameter than the inner diameter of the drain pipe and through the side wall of the body, immediately below the shelf, water-admission openings 8i are provided. In this form of the invention, the currents descending from the chemical will pass through the openings l1 and be then diverted toward the side of the body to mingle with the inflowing flushing water and then pass downwardly over the inner surface of the drain pipe.

In Figure 9, the body 82 rests upon the annular flange at the upper end of the drain pipe and is hollow in its lower portion to accommodate the inflowing flushing water which enters through the openings 83 in the side of the body. The chemical in this figure is shown as in the form of an annulus 84, the central opening of the cake registering with a central escape opening 85 in the upper portion of the body leading from the recess or chamber which holds the chemical cake. Below and in spaced relation to the outlet 85 is a shelf 86 formed integral with the side of the body immediately above the water admission openings 83 and having vertical ports 81 formed therethrough at its edge. The upper surface of the shelf 86 is inclined or sloped from its center toward its edge in all directions, as shown at 88, so that the dissolving elements from the chemical cake will be directed to and flow positively into the openings 81 and thence find their way with the flushing water down over the inner surface of the drain pipe.

In Figure 10, there is shown a body or shell having a general external dome-like form and having its base extended somewhat beyond its outer surface, as shown at 96, to rest against the annular flange and rim at the upper end of the drain pipe. Discharge ports 91 are formed vertically through the bottom of the holder at such points as to discharge immediately against the inner surface of the drain pipe, and a short stud or projection 98 is formed upon the upper surface of the bottom at the center of the same to support the chemical cake 99, which, in this form, is shown as a plug having its vertical extent somewhat greater than its diameter. The plug of chemical is held in position upon the stud 98 by a circular wall I00 extending downwardly from the top of the body and having openings llll formed through its lower end immediately above the bottom wall of the body so that the volatilizing elements of the chemical cake may flow over the bottom to the outlet ports 91. In this form of the invention, the water-admission openings are shown as obliquely disposed slots I02.

In Figure 11 a dome-like body I40 is shown having a recess MI in its top at its center to support the chemical cake I42 and having an opening I43 leading from said recess. This body rests loosely upon the upper end of the drain pipe around a disk I which is secured by screws or similar fastenings I45 to the drain pipe and has openings I46 therethrough adjacent its edge. A post Ml rises centrally from the disk M4 and at the upper end of this post is formed a tapered or conical deflector M8 having its apex directly under but spaced from the opening or post I43. Water-admission openings I49 are formed through the bottom M!) below the plane of the deflector I 48, as shown.

In all forms of the invention, the flushing water passes through the side of a body to commingle with chemical currents passing downwardly so as to carry said currents downwardly through the drain pipe and effectually deodorize and disinfect the drain pipe. While various forms of the invention have been illustrated, it will be noted that in all the forms the structure is simple and inexpensive and the operation will be certain.

Having thus described the invention, I claim:

1. A device for the purpose set forth comprising a dome-like body having an open recess in its top to encircle and support a cake of chemical and provided with an outlet in the bottom of said recess, means in the body under said outlet for deflecting streams flowing from the chemical, and means for admitting flushing water to the body to commingle with the chemical streams.
